The bundle of His is an important part of the electrical conduction system of the heart, as it transmits impulses from the atrioventricular node, located at the anterior-inferior end of the interatrial septum, to the ventricles of the heart.
24 kwi 2023 · The atrioventricular bundle (bundle of His) is a continuation of the specialised tissue of the AV node, and serves to transmit the electrical impulse from the AV node to the Purkinje fibres of the ventricles.
The atrioventricular bundle (AV bundle or bundle of His) is a tract of fibers that extends inferiorly from the AV node at the base of the right atrium. It extends from the AV node a short distance into the interventricular septum.
17 sie 2023 · The atrioventricular (AV) bundle (of His) is the initial segment of the AV node that penetrates through the fibrous trigone into the membranous part of the interventricular septum. On transverse section at the level of the fibrous body, the AV bundle may appear oval, quadrangular or triangular.
Definition. The bundle of His is a collection of heart muscle cells specialized for electrical conduction that transmits the electrical impulses from the AV node (located between the atria and the ventricles) to the point of the apex of the fascicular branches via the bundle branches.
1 maj 2023 · After electrical impulse is sent from the sinoatrial (SA) node to the atrioventricular (AV) node, the bundle of His quickly transmits the impulse to the left and right bundle branches and into the ventricles, resulting in a synchronized contraction of the ventricles. [2]
25 lip 2023 · The atrioventricular (AV) node is a small structure in the heart, located in the Koch triangle, near the coronary sinus on the interatrial septum. In a right-dominant heart, the atrioventricular node is supplied by the right coronary artery.
